[0002] Fresh cut flowers are perishable horticultural products, especially ethylene-sensitive cut flowers (such as lilies, carnations and orchids), which are easily affected by ethylene, showing symptoms such as wilting, darkening and falling of flowers. In addition, when growing in the field, fresh flowers will contact and harbor mold spores, thereby causing gray mold, which will cause the cut flowers to rot rapidly during storage. In order to extend the storage period of cut flowers, the existing technology uses low-temperature refrigeration technology to inhibit mold spores to delay the rotting process of cut flowers. However, for ethylene-sensitive cut flowers, the existing technology cannot reduce the impact of ethylene, and the cut flowers will still rot in a short time during storage. Summary of the invention

[0046] See also Figure 1-3The embodiment of the present invention provides a cut flower preservation device, which is arranged in a storage space. The cut flower preservation device includes a containing component 10 for storing cut flowers. The cut flower preservation device also includes: an identification component 11, a control component, a conveying component 12 and an O3 generating component 13. The identification component 11, the conveying component 12 and the O3 generating component 13 are all connected to the control component. The identification component 11 is used to identify the flowering state of the cut flowers. The conveying component 12 is connected between the containing component 10 and the O3 generating component 13 and is used to convey the O3 prepared by the O3 generating component 13 to the containing component 10. The control component is used to control the rate and time of conveying O3 by the conveying component 12 according to the flowering state of the cut flowers.

[0047] In this embodiment, the accommodating component 10 includes a accommodating drawer 10a and a top cover 10b. The accommodating drawer 10a is used to store cut flowers and can be made of a transparent material. The top cover is arranged on the accommodating drawer 10a. The cut flowers can be placed in the accommodating drawer 10a by pulling out the accommodating drawer 10a, or the top cover 10b can be arranged to be an open structure, so that the cut flowers can be placed in the accommodating drawer 10a by opening the top cover 10b. The identification component is arranged in the accommodating component 10, and a plurality of identification components can be arranged, for example, they can be arranged on the four sides of the accommodating drawer 10a and on the side of the top cover facing the accommodating drawer 10a, so as to fully identify all the cut flowers in the accommodating drawer 10a, so as to accurately identify all the flowering states of the cut flowers. In specific implementation, the identification component 11 can be a camera, which is used to shoot the opening state of the cut flowers in real time from various angles and transmit it to the control component. The system database of the control component stores photos of different flowers and their different opening states. After the camera takes the photos, the photos are sent to the control component. The control component uses image recognition technology to match the photos taken by the camera in real time. The O3 generating component 13 is used to prepare O3. O3 has strong antioxidant properties and can quickly decompose the ethylene released by the cut flowers during storage. Therefore, the prepared O3 is transported to the receiving drawer 10a through the conveying component 12. However, for different flowering states of the cut flowers, the rate and time of conveying O3 by the conveying component 12 are not the same. In order to better extend the storage period of the cut flowers, the control component controls the rate and time of conveying the corresponding O3 by the conveying component 12 according to the different flowering states of the cut flowers, so as to control the O3 concentration in the receiving drawer 10a within a reasonable range, effectively avoiding poisoning of the cut flowers caused by excessive gas concentration, resulting in deterioration of the cut flowers. Among them, the control component is not only used to control the conveying rate and time of the conveying component 12, but also used to control the operation of each component in the cut flower preservation device, which will be specifically described in the subsequent embodiments.

[0048] In addition, the entire cut flower preservation device is arranged in a preservation space for storage. Compared with the prior art, this embodiment also prepares O3 through the O3 generating component 13, and the conveying component 12 conveys O3 to the containing component 10 to decompose the ethylene released by the cut flowers during the storage process, and controls the rate and time of conveying O3 by the conveying component 12 according to the flowering state of the cut flowers through the control component, which can minimize the impact of ethylene on the cut flowers, thereby extending the storage period of the cut flowers.

[0049] Specifically, Figure 1-3 As shown, it also includes a CO2 generating component 14 and an illumination component 15, both of which are connected to the control component. The illumination component 15 is arranged on the containing component 10 and can illuminate the cut flowers in the containing component 10; the conveying component 12 includes a first conveying component 121 and a second conveying component 122. The first conveying component 121 is connected between the containing component 10 and the O3 generating component 13, and the second conveying component 122 is connected between the containing component 10 and the CO2 generating component 14. The second conveying component 122 is used to convey the CO2 prepared by the CO2 generating component 14 to the containing component 10.

[0050] In this embodiment, the cut flowers are still living organisms during the storage process. As long as the cut flowers are given appropriate light and carbon sources are introduced into the cut flowers, the cut flowers can still perform photosynthesis to synthesize nutrients to improve their own resistance, thereby achieving the effect of extending the storage period. Therefore, in this embodiment, it is preferred to set the lighting component 15 on the receiving component 10, specifically set on the side of the top cover 10b facing the receiving drawer 10a. The lighting component 15 can be a plurality of LED lights for providing light sources for the cut flowers. The LED lights are red and blue lights, and the ratio of red and blue lights can be set to 3:1. The light intensity is 500-1000lx, and the working time is 10-12h / 24h. The CO2 generating component 14 can prepare CO2, and the second conveying component 122 conveys the CO2 prepared by the CO2 generating component 14 to the receiving drawer 10a, thereby promoting photosynthesis. In addition, the first conveying component 121 also conveys the prepared O3 to the receiving drawer 10a, so that O3 can decompose the ethylene released by the cut flowers during the storage process to extend the storage period of the cut flowers. In this embodiment, by introducing O3 and CO2 into the cut flower storage environment (i.e., the containing assembly 10) and providing the cut flowers with appropriate light, it can not only promote the photosynthesis of the cut flowers, synthesize nutrients, and improve the disease resistance of the cut flowers, but also decompose the ethylene released by the cut flowers during the storage process, thereby extending the storage period of the cut flowers. The first conveying assembly 121 and the second conveying assembly 122 can be gas pumps.

[0051] Specifically, Figure 1-6As shown, the O3 generating component 13 includes an O3 chamber 131 for storing O3 and an O3 generator 132 arranged in the O3 chamber 131, the CO2 generating component 14 includes a CO2 chamber 141 for storing CO2 and a CO2 generator 142 arranged in the CO2 chamber 141, the first conveying component 121 is connected between the containing component 10 and the O3 chamber 131, and the second conveying component 122 is connected between the containing component 10 and the CO2 chamber 141; the control component includes a control circuit, the positive pole of the control circuit is connected to the O3 generator 132, and the negative pole of the control circuit is connected to the CO2 generator 142.

[0052] In this embodiment, the O3 generator 132 is arranged in the O3 chamber 131, the O3 generator 132 is used to prepare O3, and the O3 chamber 131 is used to store the O3 prepared by the O3 generator 132. Specifically, the O3 generator 132 includes a shell 1321, a metal panel 1322, an electric plate 1323 and an emitting electrode 1324, the emitting electrode 1324 is a needle-shaped emitting electrode, and the emitting electrode 1324 is welded on the electric plate 1323. An installation space is provided in the shell 1321, and one side of the shell 1321 is open, and the open side is connected to the installation space, and then the electric plate 1323 and the emitting electrode 1324 are installed in the installation space, and the metal panel 1322 is arranged on the open side of the shell 1321 to close the installation space, thereby forming the entire O3 generator 132; the CO2 generator 142 is arranged in the CO2 chamber 141, and the CO2 generator 142 is used to prepare CO The O2, CO2 compartment 141 is used to store CO2 prepared by the CO2 generator 142, wherein the CO2 generator 142 is made of nanomaterials (such as boron nitride nanostructures and conductive borane), and the CO2 generator 142 includes two power terminals, and the two power terminals are separated by an insulating frame so that the two power terminals cannot be energized to each other; the control component includes a control circuit board 20, the positive electrode of the control circuit board 20 is connected to the emission electrode 1324 of the O3 generator 132, and the negative electrode of the control circuit board 20 is connected to one of the power terminals of the CO2 generator 142, thereby forming a control circuit. When the control circuit is working, the control circuit board 20 passes positive electricity to the emission electrode 1324 of the O3 generator 132 through the wire 1325 so that the O3 generator 132 can ionize the air to prepare O3, and at the same time, the control circuit board 20 passes negative electricity to the CO2 generator 142 to adsorb CO2 in the air. This embodiment provides a shunt design for the control circuit, connects the positive electrode of the control circuit to the O3 generator 132 to ionize the air to prepare O3, and introduces nanomaterials into the negative electrode of the control circuit for CO2 adsorption, thereby improving the gas preparation efficiency and saving energy efficiency.

[0053] Specifically, Figure 3 and Figure 7As shown, the CO2 generator 142 includes a motor 1421 and a generator body 1422 connected to the motor 1421. The generator body 1422 is arranged on the CO2 chamber 141. The generator body 1422 has two opposite adsorption surfaces, one of which faces outside the CO2 chamber and is used to adsorb CO2, and the other adsorption surface faces inside the CO2 chamber and is used to release CO2. The motor 1421 can control the generator body 1422 to rotate so as to rotate the two adsorption surfaces back and forth inside and outside the CO2 chamber 141.

[0054] In this embodiment, the generator body 1422 includes an insulating frame, two adsorption surfaces and two power connection terminals, wherein the two adsorption surfaces are made of new nanomaterials, specifically boron nitride nanomaterials, conductive borographene and other materials, and the two adsorption surfaces are relatively arranged on both sides of the insulating frame and separated by the insulating frame so that the two adsorption surfaces are not energized to each other, and the two power connection terminals are arranged on the insulating frame, and the two power connection terminals are respectively connected to different adsorption surfaces, and the two power connection terminals are located at diagonally opposite positions of the insulating frame. When powered on, the generator body 1422 will only be connected to one power connection terminal. For the convenience of explanation, the two adsorption surfaces are divided into a first adsorption surface 14221 and a second adsorption surface 14222, and the two power connection ends are divided into a first power connection end 14223 and a second power connection end 14224. The first adsorption surface 14221 is an adsorption surface facing the inside of the CO2 chamber 141 when the power is not supplied, and is docked with the first power connection end 14223. The second adsorption surface 14222 is an adsorption surface facing outside the CO2 chamber 141 when the power is not supplied, and is docked with the second power connection end 14224. When the control circuit is working, the motor 1421 controls the generator body 1422 to rotate, and the first adsorption surface 14221 is turned toward the outside of the CO2 chamber 141. At this time, the first power terminal 14223 of the first adsorption surface 14221 is connected to the control circuit board 20, and the control circuit board 20 shunts the negative electricity to the first adsorption surface 14221. At this time, the first adsorption surface 14221 introduces external electrons, and CO2 combines with the external electrons and is then adsorbed on the first adsorption surface 14221 for enrichment. At this time, the second adsorption surface 14222 faces the inside of the CO2 chamber 141, and the second power terminal 14224 is away from the end of the control circuit that is energized, so that the second power terminal 14224 cannot be connected to the control circuit board 20, and the second adsorption surface 14222 does not adsorb CO2. After the predetermined adsorption time, the generator The body 1422 is turned under the control of the motor, and the first adsorption surface 14221 is turned back to the CO2 chamber 141, and the second adsorption surface 14222 is turned outside the CO2 chamber 141. At this time, the first power terminal 14223 is disconnected from the control circuit board 20, and the outer electrons on the first adsorption surface 14221 are removed. The CO2 adsorbed on the first adsorption surface 14221 is automatically desorbed (that is, CO2 is separated from the adsorption surface) and temporarily stored in the CO2 chamber. At the same time, the second power terminal 14224 is connected to the control circuit board 20, and the second adsorption surface 14222 introduces outer electrons. CO2 combines with the outer electrons and is then adsorbed on the second adsorption surface 14222 for enrichment. After the predetermined adsorption time, the second adsorption surface 14222 is turned back to the CO2 chamber 141 for desorption, and this is repeated.

[0055] In a specific implementation, in order to better store CO2, a sealing ring 143 is provided around the CO2 generator 142. The sealing ring 143 is made of materials such as silicone and brush hair, so that the CO2 chamber 141 is relatively sealed.

[0056] Specifically, Figure 3 As shown, the cut flower preservation device further includes a sensor assembly 16 connected to the control assembly. The sensor assembly 16 includes a CO2 sensor 161 disposed in the containing assembly 10 for detecting the CO2 concentration in the containing assembly 10.

[0057] In this embodiment, in order to promote photosynthesis, it is necessary to control the CO2 concentration in the containment component 10 within a preset concentration range. Therefore, a CO2 sensor 161 is provided in the containment component 10 to detect the CO2 concentration in the containment component 10 in real time. If the CO2 concentration in the containment component 10 is not within the preset concentration range, the CO2 in the CO2 compartment 141 is transported to the containment component 10 through the second transport component 122 to meet the preset concentration range. It should be noted that when the storage space is not sterilized, the CO2 concentration in the air is about 0.3ppm, and there is no need to additionally transport CO2 to the containment component 10.

[0058] Specifically, Figure 1-3 As shown, the sensor assembly 16 includes a temperature sensor 162 and a humidity sensor 163, which are used to detect the temperature and humidity of the receiving assembly 10 respectively;

[0059] The cut flower preservation device also includes a humidifying component 17 connected to the control component, and the humidifying component 17 is also connected to the containing component 10. The control component is used to control the opening and closing of the humidifying component 17 to control the humidity of the containing component 10. The identification component 11 can also be used to identify the type of cut flowers. The control component is also used to control the temperature of the containing component 10 according to the type of cut flowers.

[0060] In this embodiment, in order to extend the storage period of the cut flowers, the cut flowers can be refrigerated at low temperatures and humidified. Specifically, the identification component 11 can also identify the type of the cut flowers and transmit the image to the control component. The identification method can refer to the identification method of identifying the open state of the cut flowers in the previous embodiment. The control component controls the temperature of the containing component 10 according to the type of the cut flowers, which can be specifically controlled according to Table 1:

[0061] Table 1 Temperature control logic

[0062]

[0063] The control component controls the temperature in the receiving component 10 according to the data detected by the temperature sensor 162 and the type of cut flowers. In addition, the humidity in the receiving component 10 also needs to be controlled within a predetermined humidity range. The humidity sensor 163 detects the humidity in real time. If the humidity is too low, the control component controls the humidification component 17 to humidify so that the humidity in the receiving component 10 reaches the predetermined humidity range, that is, the humidification component 17 is turned on when the humidity is lower than 80%, and stops when the humidity reaches 90%. These two methods can also extend the storage period of cut flowers.

[0064] Specifically, Figure 1 and Figure 3 As shown, the O3 chamber 131 is provided with a damper 1311, and when the damper 1311 is opened, the O3 in the O3 chamber 131 can be released into the storage space.

[0065] In this embodiment, the damper 1311 is arranged on the O3 chamber 131, preferably on the top of the O3 chamber 131. When it is detected that the O3 concentration in the O3 chamber 131 reaches 500-1000 ppb, the damper 1311 is opened. At this time, the O3 in the O3 chamber 131 is released into the storage space for sterilization, wherein the damper 1311 can be opened for 6-8h / 24h.

[0066] Specifically, Figure 1 and Figure 2 As shown, a moisture permeable membrane 18 is provided on the receiving assembly 10 .

[0067] In this embodiment, the moisture-permeable membrane 18 is disposed on the top cover 10b of the container assembly 10, and its function is to allow water vapor to be discharged while preventing external moisture from entering, thereby helping to maintain a suitable humidity in the container assembly 10, reducing the risk of mildew and rot, and thus extending the storage period of cut flowers.

[0068] Specifically, the cut flower preservation device also includes a pressure relief component 19, which is used to relieve pressure in the storage space (including the storage component 10 for storing cut flowers, the O3 chamber 131 for storing O3, and the CO2 chamber 141 for storing CO2) to prevent structural damage or explosion caused by too much gas and excessive pressure. Therefore, the storage component 10, the O3 chamber, and the CO2 chamber are all equipped with a pressure relief component 19. When it is detected that the pressure in the corresponding space is greater than the preset pressure value, the pressure relief component 19 automatically opens to exhaust and relieve pressure. When it is detected that the pressure in the corresponding space is less than or equal to the preset pressure value, the pressure relief component 19 automatically closes. Among them, the preset pressure value can be set to 0.5-0.7MPa, and the pressure relief component 19 can be a gas valve.

[0069] like Figure 8 As shown, the embodiment of the present invention further provides a cut flower preservation method, which is applied to the cut flower preservation device as described above, and includes S10-S30:

[0070] S10, turning on the O3 generating component 13 to prepare O3;

[0071] S20, obtaining the flowering state of the cut flowers in the containing component 10;

[0072] S30, controlling the speed and time of O3 conveying by the conveying assembly 12 according to the blooming state of the cut flowers.

[0073] In this step, the O3 generating component 13 is turned on by the control component, that is, the control circuit board 20 starts working, and the positive electricity is passed to the O3 generator 132 to ionize the air to prepare O3, and the O3 is stored in the O3 chamber 131. The control component identifies the flowering state of the cut flowers in the containing component 10 through the identification component 11, and controls the working efficiency (i.e., the rate and time of conveying O3) of the conveying component 12 (mainly referring to the first conveying component 121) according to the flowering state of the cut flowers. When the working time reaches the preset working time, the conveying component 12 is closed to stop conveying O3. In this step, O3 is conveyed to the containing component 10 by the conveying component 12, and the rate and time of conveying O3 by the conveying component 12 are controlled according to the flowering state of the cut flowers, so that the O3 concentration in the containing component 10 is within a reasonable range, which can not only decompose the ethylene released by the cut flowers during the storage process, but also avoid the cut flowers from being poisoned by too high O3 concentration, resulting in the deterioration of the cut flowers.

[0074] Specifically, Fig. 9 As shown, S30 includes S31-S33:

[0075] S31, obtaining the flowering status of all the cut flowers in the containing assembly 10, and confirming the quantity ratio of the corresponding cut flowers in each flowering status;

[0076] S32, judging whether the quantity ratio of the corresponding cut flowers in the flowering state meets the corresponding conveying conditions;

[0077] S33. If the corresponding transport condition is met, determine whether the number of the corresponding transport conditions that are met is multiple. If so, select a group of transport parameters with the highest priority according to the preset priority to control the transport component 12. Otherwise, directly control the transport component 12 according to a group of transport parameters corresponding to the met transport condition, wherein each transport condition corresponds to a group of transport parameters, each transport condition has a corresponding priority, and each group of transport parameters includes the rate and time of transporting O3.

[0078] In this step, O3 can decompose ethylene, so O3 is transported to the containing assembly 10. However, the amount of ethylene released by cut flowers in different flowering states is different (e.g. Fig.10 As shown), the required O3 concentration is also different. Therefore, the O3 delivery rate and time of the delivery component 12 can be controlled according to Table 2 for different flowering states:

[0079] Table 2O3 control logic

[0080]

[0081] Among them, ① bud stage: the buds are not open; ② petal stage: the top of the buds are slightly opened, revealing the color of the petals; ③ initial opening stage: the buds continue to open, the petals extend from the buds, but are not fully open, and the stamens are not visible; ④ full bloom stage: the petals are in full bloom, revealing the stamens.

[0082] The control component identifies the flowering state of all the cut flowers in the containing component 10 through the identification component 11, and confirms the quantity ratio of the corresponding cut flowers in each flowering state, and refers to Table 2 to determine whether each flowering state meets the conveying condition. The conveying condition here means whether the quantity ratio of the cut flowers in each flowering state reaches the quantity ratio in Table 2. If it has reached, the conveying component is controlled to convey O3 according to the O3 conveying rate and O3 conveying time in Table 2. If the number of flowers that meet the corresponding conveying condition is multiple, that is, the cut flowers in multiple flowering states all meet the corresponding quantity ratio in Table 2, at this time, the highest set of conveying parameters is selected according to the preset priority to control the conveying component 12, wherein the preset priority can refer to the control flow in Table 2, and the larger the number in the control flow, the higher the priority. For example, when the flowering state of the cut flowers is that the quantity ratio of the petal exposure period meets 50%, and the quantity ratio of the full bloom period meets 50%, and the conditions of control flow 2 and 6 are met at the same time, the control flow 6 will be operated. If the number of flowers that meet the corresponding conveying condition is one, the conveying component 12 is directly controlled according to the set of conveying parameters corresponding to the satisfied conveying condition. This step controls the O3 concentration within a reasonable range by real-time monitoring of the flowering state of the cut flowers, thereby preventing the cut flowers from being poisoned by excessive gas concentration and causing them to deteriorate.

[0083] Specifically, Fig.11 As shown, the cut flower preservation method also includes:

[0084] S40, when the first conveying assembly 121 is closed, the damper 1311 is opened to release the O3 in the O3 chamber 131 to the storage space, and the damper 1311 is closed after a predetermined period of time.

[0085] In this step, after the first conveying component 121 works for a predetermined time, the first conveying component 121 stops working, and the damper 1311 is opened at this time. The O3 in the O3 chamber 131 enters the storage space through the damper 1311 to sterilize the space. The damper 1311 can be opened for 6 to 8 hours. After the sterilization is completed, the damper 1311 is closed.

[0086] Specifically, Fig.12 As shown, the cut flower preservation method also includes:

[0087] S50, obtaining the CO2 concentration in the containing component 10;

[0088] S60, determining whether the CO2 concentration reaches a predetermined concentration range, and if not, turning on the second transport component 122 and the illumination component 15.

[0089] In this step, it is necessary to control the CO2 concentration in the containing component 10 within a predetermined concentration range to promote photosynthesis. Therefore, the CO2 sensor 161 detects the CO2 concentration in the containing component 10 in real time. If the CO2 concentration does not reach the predetermined concentration range, the CO2 in the CO2 compartment 141 is transported to the containing component 10 through the second conveying component 122. At the same time, the illumination component 15 is turned on, and the working time of the illumination component 15 can be 10 to 12 hours. In this step, the prepared CO2 is passed into the containing component 10, and appropriate illumination is given to the cut flowers, thereby promoting the photosynthesis of the cut flowers to synthesize nutrients, improving the disease resistance of the cut flowers, and thus extending the storage period. It should be noted that when the O3 generating component 13 is turned on to prepare O3, the CO2 generating component 14 is also preparing CO2. This is because the positive electrode of the control circuit is connected to the O3 generating component 13, and the negative electrode of the control circuit is connected to the CO2 generating component 14. Therefore, when the control circuit board 20 starts working, the positive current flows to the O3 generating component 13, and the negative current flows to the CO2 generating component 14. Therefore, in this step, when it is detected that the CO 2 concentration does not reach the predetermined concentration range, the CO 2 prepared in the CO 2 chamber 141 can be directly transported to the containing component 10 through the second transport component 122 .
